The Double Vibration Source Screen, also known as a direct discharge vibrating screen, is a highly efficient screening device widely used in powder production lines for impurity removal and material loosening. This screening equipment utilizes either a single or double horizontal vibration motor as its excitation source, generating an elliptical motion trajectory of materials on the screen surface. The unique design and working mechanism of this screen make it an essential tool in industries such as food processing, chemicals, pharmaceuticals, and mining, where precise and efficient screening is required.
With its durable structure, customizable screen options, and strong vibration intensity, the Double Vibration Source Screen ensures high processing efficiency, reduced material clogging, and optimized screening performance.
Structural Features of the Double Vibration Source Screen
This screening equipment is composed of several key components that contribute to its durability and efficiency:
1. Screen Frame
The screen frame is typically constructed using high-quality steel materials, ensuring it can withstand both the weight of materials and the stress generated by vibrations. Its reinforced structure enhances the machine’s stability, prolonging its operational lifespan.
2. Screen Mesh
The screen mesh is a crucial component that determines the precision of the screening process. It is available in various materials and aperture sizes, allowing customization based on the specific material being processed. The high-strength and wear-resistant mesh ensures long-lasting performance and minimal clogging.
3. Vibration Motor
The vibration motor serves as the power source of the screening machine. It is available in single-motor or dual-motor configurations, depending on the required vibration intensity and processing capacity. The unique motor installation design induces linear vibration, which efficiently moves materials across the screen surface.
Working Principle of the Double Vibration Source Screen
The operating mechanism of this screening machine ensures fast and efficient material separation:
- Vibration Activation – Once the vibration motor is activated, it generates a linear excitation force that causes the screen body to vibrate perpendicular to the screen surface.
- Material Movement – Under the influence of vibration, materials move in a straight-line trajectory along the screen surface.
- Separation Process –
- Fine particles that are smaller than the screen openings pass through the mesh and are collected as undersized material.
- Larger particles that cannot pass through the mesh continue moving forward and exit through the discharge outlet, completing the screening process.
This efficient screening mechanism allows for rapid material classification, impurity removal, and uniform particle distribution.
